PRINTING-MACHINE.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed June 15,1906. Serial No- 321,801.

To aZZ whom it may concern.-

Be it known that I, AxEL V. BEEKEN, a citizen of the United States ofAmerica, and a resident of Newark, Essex county, State of New Jersey,have invented certain new and useful Im rovements in PrintingMachines,of which t e following is a specification.

The present invention relates generally to rinting-machines, and hasmore particuarly reference to a machine for printing and perfecting websof calico, paper, or other materials.

The object of the invention is to simplify the construction of machinesof this character.

The invention consists in providing two web-reversers standingsubstantially parallel to the axis of the impression member, betweenwhich reversing members the web is reversed by a single twist andbrought back with its other side out in the same transverse plane.

In the drawings, Figure 1 is an end elevation, with the frameworkremoved, of so much of a printing-machine as is necessary to theunderstanding of the invention, embodying the invention. Fig. 2 isasectional view on line 2 2 of Fig. 1. Figs. 3 and 4 show modificationsof the structure disclosed in Figs. 1 and 2.

Similar numerals of reference indicate corresponding parts in thedifferent views.

The form of printing-machine disclosed is of the type commonly known ascalicoprinting machine, although the invention may be employed for thepurpose of printing on paper or other material as well.

1. indicates the impression member, which in this instance consists of asingle cylinder.

2 and 3 indicate a plurality of form members, which in the presentinstance are shown as the ordinary engraved copper cylinders sogenerally employed in printing calico. Form members of a differentnature may of course be used. These form members run in theink-fountains 4 and are mounted in the movable bearings 5, ada ted toslide in the guides 6 and there be he d in position by means or theset-screws 7.

Around the impression member and the idler 8 asses the usual blanket 9,so as to make t e surface of the cylinder sufficiently yielding. Inaddition to this the roll-tympan 10 is provided for receiving the offsetwhen the printed side of the web is brought against the cylinder. Thisroll-tympan may pass from the roll 11 to the roll 12.

The web 13 is led over the idler 14 and down around the impressionmember, where it receives an impression on one side 15. It is then ledover the idler 16 and under the bar or roller 17. The axis of this baror roller is substantially parallel to the axis of theimpression-cylinder. 18 indicates another bar or roller, also parallelto the axis of the impression member. As the web passes between thesetwo rollers 17 and 18 it is reversed by a single twist, so as to bringits unprinted side 19 out and the printed side in. From the roller 18the web passes up around the idler 20 and then around the impression-eylinder on the other side thereof. The web is now printed onits other side and is led out of the machine over the idler 21. It willbe noticed that not only is the web reversed, but it is brought back inthe same plane transversely. If desired, a roll-tympan may pass from thespindle 23 to the spindle 24.

In Figs. 3 and 4 are shown modifications in which the impression memberconsists of two cylinders 25 and 26, in one case placed side b y sideand in the other case superposed. The operation here is the same as inthe structure disclosed in Fig. 1.

\Vhen it is desired to print on one side only of the web, the latter isled. around the cylinder in the usual way without passing through therollers for reversing the same.

WVhat is claimed is In a web-printing machine, the combination of animpression member, a plurality of coacting form members grouped aroundthe said impression member but located in the same transverse plane, twoweb-reversers standing substantially parallel to the axis of theimpression member between which the web is reversed by a single twistand brought back with its other side out in the same transverse plane,and guide-rolls for leading the web around the impression member.

Signed at New York city this 8th day of June, 1906.
